None of them.
You may have neglected to copy something else that goes with the question, as there are no "above lines".

|_ example of a perpendicular line is shown above:
It is C which has no perpendicular or parallel lines
The addition sign is formed by two intersecting lines, as is the cross. The two lines are perpendicular to each other.
Perpendicular lines are two lines that intersect at a 90-degree angle, forming a right angle where they meet. In geometric terms, the slopes of perpendicular lines are negative reciprocals of each other. Visually, perpendicular lines appear to be at right angles to each other, creating a distinct "L" shape where they intersect.
= parallel + perpendicular As such no, perpendicular lines do not naturally have parallel lines. However...connect the lines in the symbols below. ++ ++ And you'll have 4 perpendicular lines, and 4 parallel lines.

Magnetic field lines are usually depicted as curved lines extending away from the source. They are neither parallel or perpendicular (though they appear more parallel than perpendicular).
